STRUCTURAL GLASS DESIGN PHILOSOPHY & STRUCTURAL SAFETY

This chapter presents and discusses the principles, methods and the associated limitations that currently are seen as the state-of-the-art in structural safety. The basis for understanding the design philosophy of modern design codes is provided. Innovative concepts in safety, starting with definitions of risk, reliability, fragility and a new definition of structural robustness are presented. Uncertainties are discussed and a risk management framework for structural design is proposed. A probabilistic structural design philosophy is presented detailing a new methodology for analysing structural fragility and the robustness of structures against failure. An example is presented determining the robustness of a falsework structure against collapse. Strategies to enhance structural robustness and structural safety are given. An improved design methodology for temporary structures is presented and detailed, and an example is provided. Finally, the chapter discusses the use of reduction factors when determining design action values for the design of temporary structures.

Do So

The Society's All-Day Discussion on Aircraft Design Philosophy was extremely well supported and at one stage there were more than 350 members and visitors present. As is inevitable on these occasions there was insufficient time available for all those who wished to make a contribution to do so, even though the four lecturers had reduced their contributions to a bare minimum by presenting summarised versions of their papers.With such an all-embracing title as Aircraft Design Philosophy it was obvious that some main channel of exploration would have to be chosen; that which evolved during the planning of this event was structural safety, as will be apparent from the discussion. The preparation of a summary of discussions presents a number of problems.
